Consider the following terms: A. Lightning, B. Landslide, C. Thundering, D. Tsunami, E. Floods. Earthquakes can cause:

  1. A.B, D and E
  2. B.A, B and C
  3. C.B only
  4. D.B and E

Correct answer

A. B, D and E

Explanation

The correct answer is A, B, D and E, that is landslide, tsunami and floods. An earthquake is the shaking of the ground when energy stored along a fault is suddenly released, and that shaking sets off further hazards. On a steep slope the tremor loosens soil and rock and brings down a landslide. Under the sea, a sudden movement of the ocean floor lifts a huge column of water and sends out a tsunami, as in the Indian Ocean in December 2004. Floods follow when the shaking cracks a dam or an embankment, or when a landslide dams a river and the water later bursts through. Option B is wrong because lightning and thundering are weather events born in tall cumulonimbus clouds and have nothing to do with movement inside the earth. Option C is wrong because it keeps only the landslide and leaves out the tsunami. Option D is wrong because it adds floods but still misses the tsunami. Exam tip: earthquake – landslide, tsunami and dam-burst floods; lightning and thunder belong to a thunderstorm.

Which of the following statements is/are correct? 1. Himalayan rivers have their origin in the snow-covered areas, hence are dry in winter season. 2. Rivers of the Peninsular Plateau have reached maturity. 3. Himalayan rivers depict all the three stages of normal cycle of erosion. Select the correct answer using the code given below.

  1. A.2 only
  2. B.1 and 3 only
  3. C.2 and 3 only
  4. D.1, 2 and 3
Show answer
Correct answer: C. 2 and 3 only

Himalayan rivers are perennial, so statement 1 is wrong, while statements 2 and 3 are correct. Himalayan rivers such as the Ganga, Indus and Brahmaputra rise from glaciers and snowfields and also get monsoon rain, so they flow all year round, including in winter.

Q3.GeographyAsked in: CDS · CDS-II 2017, GKMedium

Which of the following statements related to latitude are true? 1. Rainfall, temperature and vegetation vary with latitude. 2. The difference between the longest day and the shortest day increases with latitude. 3. Indira Point is located approximately at 6°45' N latitude. Select the correct answer using the code given below.

  1. A.1 and 2 only
  2. B.1 and 3 only
  3. C.2 and 3 only
  4. D.1, 2 and 3
Show answer
Correct answer: D. 1, 2 and 3

All three statements about latitude are true. Latitude decides how directly the Sun's rays strike a place, so temperature, rainfall and the type of vegetation change from the equator towards the poles, from hot, wet rainforests to cold tundra.
